Evelyn,
Just a few things we really need to know
Firstly how old are you ?
How tall?
Long or short arms?
Physical strength ?
Gee, starting to sound like dating site.
This is important because Honda's are very very easy to pull start where as the Briggs engines are not.
I do exchanges for a lot of my older women who have good mowers that they can no longer start because they can not pull them.
Or have bought a brand new one from a glass front that won't let you test start the mower in the shop, they get them home then find if they are holding the bails closed they can not pull the starting rope.
Some mowers have adjustable handles so shorter people will not be pushing a handle that is at chest height or taller people are pushing from knee height.
Next we really need to know a little about your grass and what you like to do , throw, mulch or bag.?
What type of grass do you have ?
How big is your yard ?
It is really worth while to go to a mower shop and do some test starts just to make sure you can do it.
And beware of the salesman who shows you how to start a mower and gives it an almighty pull.
Once the mower has been started from cold most are a lot easier to restart where as starting from cold is generally a harder pull.
